WP-20P - Weldcraft W-225 Pencil Water-Cooled TIG Torch Body (WP-20P)

Technical Overview: Weldcraft W-225 (WP-20P) Torch Body

The Weldcraft W-225, commonly referred to by its legacy SKU WP-20P, is a specialized water-cooled TIG torch body designed for the 20 Series platform. It is distinguished by its 180-degree pencil configuration, which aligns the tungsten electrode directly with the torch handle axis. This geometry is critical for bore welding, internal pipe cladding, and applications where the radial clearance is insufficient for a standard angled torch head. The unit is rated for a welding output of 225 Amps at 100% duty cycle (dependent on cooling system efficiency), utilizing a closed-loop water cooling system to dissipate heat from the power cable and torch head.

Mechanically, the WP-20P integrates seamlessly with existing 20 Series consumables. It accepts standard collets, collet bodies, and gas lenses, allowing operators to utilize their existing inventory of front-end parts. The torch body features robust insulation and high-conductivity copper components to ensure stable arc transfer and thermal management. The water cooling passages are designed to circulate coolant around the head assembly effectively, preventing the resistive heating that typically limits the duty cycle of air-cooled pencil torches.

Installation requires a compatible power cable and water hose setup typical of the W-225 / WP-20 series. The rigid body construction provides a stable platform for the electrode, ensuring consistent arc length control even when the operator is extending the torch into deep cavities. The handle design is optimized for grip and thermal isolation, protecting the welder's hand from radiant heat during high-amperage operation.

Specifications and Compatibility

• Amperage Rating: 225 A (DC/AC)
• Cooling Type: Water-Cooled
• Head Angle: 180 Degrees (Straight/Pencil)
• Series Compatibility: Weldcraft 20 Series (W-250, W-225)
• Electrode Capacity: Compatible with standard tungsten diameters supported by 20 Series collets (typically up to 1/8").

For MRO and industrial applications requiring specific access solutions without sacrificing amperage capability, the WP-20P serves as a high-performance replacement body for the W-225 Pencil system.
